A food testing sample preservation device

Abstract

The invention belongs to the technical field of storage devices, and in particular relates to a storage device for food testing samples; it includes a main body shell, and the main body shell divides the interior into an opening layer, a storage layer and an air tank layer through a lower partition and an upper partition. Set the thermal insulation lining of the gas tank layer and the low-temperature nitrogen tank. The low-temperature nitrogen tank is connected to the gas valve interface and the branch pipe through the gas tank interface. The preservation layer is provided with the insulation lining of the preservation layer, the lower partition is provided with a placement seat, and a preservation bottle is arranged in the placement seat; the top of the main body shell is connected to the top cover, and the top cover includes a top cover plate, and an outer ring plate and an inner ring plate are arranged on the bottom surface of the top cover plate. A ring plate, a lower opening is arranged on the top cover; a rotating shaft is arranged on the top cover, and the rotating shaft is connected to the opening cover, and the opening cover includes a fan-shaped cover plate, and an upper opening is arranged on the fan-shaped cover plate; the invention has reasonable structure, convenient operation, and can effectively Isolate the inside and outside, stabilize the moisture of the sample, and avoid the contamination of the sample by the external air.

Description

Technical field [0001] The present invention belongs to the technical field of storage devices, and more particularly to a food detection sample storage device. Background technique [0002] As the material living standards continue to increase, people can eat food types continue to be rich, in order to ensure food safety, determine food beneficial or harmful ingredients, need to be tested against related foods; before testing related food, first need to collect and Preparation of food samples, prepared samples should be analyzed in a short period of time. If it is not possible, it is necessary to carry out good preservation of food samples, prevent pollution, if it is stored, it is easy to cause samples to absorb or lose water, and fluid Phenomenon such as high temperature decomposition, fermentation or mildew, etc., which causes the sample component to change, which in turn affects the test results, and even leads to an error conclusion. After the detection, the food sample sho...

Problems solved by technology

[0002] With the continuous improvement of material living standards, the types of food that people can eat are constantly enriched. In order to ensure food safety and determine the beneficial or harmful ingredients of food, it is necessary to test related foods; before testing related foods, it is first necessary to collect and Prepare food samples. The prepared samples should be analyzed and tested in a short time. If it cannot be carried out immediately, the food samples should be well preserved to prevent contamination. If not properly preserved, it is easy to cause water absorption or loss of water, photolysis of the sample Phenomena such as pyrolysis, fermentation or mildew will change the composition of the sample, which will affect the test results and even lead to wrong conclusions. After the test, the food samples should be properly preserved for a period of time in case of re-examination when necessary; However, the existing storage device mainly provides refrigeration function, which cannot protect the moisture in the sample, and is easily polluted by external air, and the sealing performance needs to be improved. Therefore, it is necessary to provide a storage device that can maintain the original state of the food sample. of
